Abstract

La présente invention concerne des membranes asymétriques composées d'un substrat microporeux dont les pores contiennent un gel réticulé dont la densité à l'emplacement ou à proximité immédiate de l'emplacement de la surface principale de la membrane est supérieure à la densité à l'emplacement de l'autre surface principale. Les membranes de l'invention sont utilisées pour séparer la matière des liquides et offrir un bon échange et un bon rejet à basse pression.
